WebSome molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. WebSome small molecules such as water, oxygen and carbon dioxide can pass directly through the phospholipids in the cell membrane. Larger molecules such as glucose require a specific transport...
